Abstract
The utility model belongs to the field of plant respiration determination and relates to a package type connector. The package type connector comprises a cylinder, wherein the cylinder has a hollow structure and is composed of two semicircular members and one sides of the members are connected through a movable shaft; a measurement opening which is communicated with the interior of the cylinder is formed in the side surface of the cylinder; and an airtight sponge layer is arranged on the inner side surface of the cylinder. The package type connector is simple in structure and low in cost; with the openable cylinder structure, the connector does not need to be fixed on the tree trunk for a long time so that the measuring instrument can be connected with the tree trunk conveniently; besides, the consumption of a connecting material is avoided and the tree body is protected against damage; and the package type connector can be reused and provides guarantee for measurement of the respiration rate of the tree trunk.
Description
Technical field
The utility model platymiscium respiration monitoring field relates to a kind of connector, is a kind of packaging type connector specifically.
Background technology
It is to explain one of critical process that the forest ecosystem yield-power changes that trunk is breathed, and measures the trunk respiratory rate, understands its coenocorrelation regulatory mechanism, helps to make up the Forest Carbon circulation model, and the estimation precision of Forest Carbon revenue and expenditure is provided.In recent ten years, because Atmospheric CO
2The lasting rising of greenhouse gases concentration, trunk is breathed the focus that has become research.The method of measuring the trunk breathing is more, and early stage general gas exchange method and the sealing method of adopting in recent years, mainly is to utilize portable photosynthetic mensuration system (Li-Cor6400) to measure the trunk respiratory rate.
In the process of measuring the trunk breathing, determining instrument is connected employing connector connection usually with trunk, at present, the connector of use is generally abutment ring, an end that is abutment ring is placed in trunk surface, and the other end is connected with the soil respiration air chamber horizontal seal of portable light assembly system analyser.Abutment ring commonly used is the PVC ring, is adhered to trunk surface by glue, measures again, discloses with the PVC abutment ring as China's patent 03133609.4 to be connected with trunk, and abutment ring adopts silica gel, waterproof gasket cement to be connected with trunk.The advantage of using the PVC abutment ring be can extended immobilization in trunk surface, can carry out repetition or METHOD FOR CONTINUOUS DETERMINATION and long-term the measurement, shortcoming is that large scale measurement will consume a large amount of connection materials, cost is higher, connect by bindings such as silica gel in addition, the bark of bond site can't be breathed, produce necrosis, grievous injury tree body.
The utility model content
The purpose of this utility model is to provide a kind of packaging type connector at the deficiencies in the prior art, adopt the open-close type cylindrical structure, need not with the connector extended immobilization on trunk, make things convenient for determining instrument to be connected with trunk, avoid connecting material consumption, avoid setting the body injury.
The technical scheme that the utility model adopted:
A kind of packaging type connector comprises right cylinder, and described right cylinder adopts hollow structure, is made of two semi-circular members, and a side of member connects by movable axis, and making between the member can opening and closing, closes the right cylinder of fashionable formation hollow; At the measurement mouth of cylindrical side setting with the right cylinder internal communication, be used for being connected with determining instrument, cylindrical medial surface is provided with airtight spongy layer, damage bark in the time of both can having avoided right cylinder to be fixed on trunk can make cylindrical internal diameter meet the stem girth of trunk to be measured by the thickness of regulating sponge again.
The folding side of described cylindrical two semi-circular members is provided with snap device, can close two fashionable member fastenings, avoids that two semi-circular members unclamp in the mensuration process, and influence is measured.
The utility model is simple in structure, and is with low cost, adopts the open-close type cylindrical structure, need not with the connector extended immobilization on trunk, make things convenient for determining instrument to be connected, both avoid connecting material consumption with trunk, can avoid injury tree body again, reusable, for the measurement of trunk respiratory rate provides safeguard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, right cylinder; 2, semi-circular member; 3, spongy layer; 4, movable axis; 5, measure mouth.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and instantiation, but not as to qualification of the present utility model.
In structure shown in Figure 1, the utility model comprises the right cylinder 1 of hollow, right cylinder 1 is made of two semi-circular members 2, one side of member connects by movable axis 4, and making between the member can opening and closing, closes the right cylinder of fashionable formation hollow, the opposite side of member (folding side) is provided with snap device, can close two fashionable member fastenings, avoid that two semi-circular members unclamp in the mensuration process, influence is measured; At the measurement mouth 5 of the side of right cylinder 1 setting with the right cylinder internal communication, be used for being connected with determining instrument, cylindrical medial surface is provided with airtight spongy layer 3, damage bark in the time of both can having avoided right cylinder to be fixed on trunk can make cylindrical internal diameter meet the stem girth of trunk to be measured by the thickness of regulating sponge again.
During measurement, right cylinder 1 is fixed on the trunk to be measured, then with the determining instrument horizontal seal to measuring on mouthfuls 5, can breathe trunk and measure.After measuring, take off determining instrument, then the snap device on the right cylinder 1 is opened, take off right cylinder 1, carry out the next one again and measure.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. packaging type connector is characterized in that: comprise right cylinder, described right cylinder adopts hollow structure, is made of two semi-circular members, and a side of member connects by movable axis; At the measurement mouth of cylindrical side setting with the right cylinder internal communication, cylindrical medial surface is provided with spongy layer.
2. packaging type connector according to claim 1 is characterized in that: the folding side of described cylindrical two semi-circular members is provided with snap device.
